product2-lgFrom simple alarms to sophisticated systems integrating fire and gas detection, logic controls, graphical interface and remote web server displays, the Sierra Monitor Sentry IT Controller is “Best of Class”.

The Sentry controller heritage continues to emphasize Information Technology as a key ingredient of system design. The capability of simultaneous interface via analog 4-20 mA, RS-485 Modbus, Relay contact and SentryBus insures that both new and legacy sensor modules can be deployed.

Sentry Commander Logic insures that complex algorithms such as zone voting, delay timing, multiple unique alarm levels and other special requirements can be implemented with simple user configuration at the spreadsheet level.
